Description
editHibbertia incompta is a weakly stemmed, often prostrate shrublet that typically grows to a height of up to 30 cm (12 in) and has hairy foliage. The leaves are linear to elliptic, 35–70 mm (1.4–2.8 in) long and 3–8 mm (0.12–0.31 in) wide and sessile or on a petiole up to 3 mm (0.12 in) long. As the leaves age, the edges roll under and the leaves become narrower. The flowers are arranged singly in leaf axils on a thick peduncle 15–25 mm (0.59–0.98 in) long, with linear bracts about 2.5 mm (0.098 in) long. The five sepals are joined at the base, the two outer sepal lobes 9.3–10.2 mm (0.37–0.40 in) long and the inner lobes slightly longer. The five petals are wedge-shaped to egg-shaped with the narrower end towards the base, yellow, about 9 mm (0.35 in) long. There are 45 to 60 stamens arranged in groups around the two or three carpels, each carpel with four ovules.[2][3]
Taxonomy
editHibbertia incompta was first formally described in 2010 by Hellmut R. Toelken in the Journal of the Adelaide Botanic Gardens from specimens collected near Jabiru in 1981.[2][4] The specific epithet (incompta) means "inelegant", referring to the wildly spreading hairs on the lower side of the leaves.[2][5]
Distribution and habitat
editThis hibbertia grows in woodland in sandy soil below the Arnhem Land Plateau in the northern part of the Northern Territory.[2][3]
Conservation status
editHibbertia incompta is classified as "data deficient" under the Territory Parks and Wildlife Conservation Act 1976.[3]
